Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467992, here are decompositions:

  • 29 + 2147467963 = 2147467992
  • 71 + 2147467921 = 2147467992
  • 73 + 2147467919 = 2147467992
  • 179 + 2147467813 = 2147467992
  • 191 + 2147467801 = 2147467992
  • 199 + 2147467793 = 2147467992
  • 223 + 2147467769 = 2147467992
  • 233 + 2147467759 = 2147467992

Showing the first eight; more decompositions exist.
